This equipment is specially used for producingΦ32-Φ89mm, δ1.5-4.5mm high-frequency straight seam welded pipe and corresponding square pipe.
The composition of equipment is from uncoiler to fixed length cutting saw.
Rolling speed can be according to suitable range of pipe diameter and wall thickness.
Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.

Welded steel pipe, also called welded pipe, is a steel pipe made by welding and forming a steel plate or strip steel.
It is usually 6 meters long.
The welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and low equipment investment, but the general strength is lower than that of seamless steel pipe.
